Operation using Straight Key/External Keying Device
When using a straight key, an external electronic keyer, or a computer-generated keying
device, please follow the instructions in this section.
1. Insert your key’s (three-conductor) plug into the rear-panel
KEY jack.
2. Press the / key, as needed, to select one of the CW (CW/CWR)
modes.
The “CW” mode utilizes USB-side carrier injection, while the CWR (Reverse)
mode utilizes LSB-side injection.
3. Press the key momentarily, then then rotate the knob, as needed, until Oper-
ating Function Row 10 [VOX, BK, KYR] appears on the display.
4. Press the (BK) key, as needed, to activate “Semi Break-In” operation. The “

” icon
will appear at the right of the “BK” indication.
5. The CW hang time can be adjusted using Menu #17 (CW DELAY). To adjust the CW
hang time:

Press and hold in the key for one second to enter the Menu mode.

Rotate the knob to select Menu #17 (CW DELAY).

Rotate the knob to select a longer or shorter delay time (default: 250 ms).
This transceiver was not expressly designed for “full QSK” operation, the minimum
(10 ms) setting of this Menu item (CW DELAY) will be very close to full break-in
performance.

When done, press and hold in the key for one second to save the new setting
and exit to normal operation.
If you are already in Operating Function Row 10
[VOX, BK, KYR]
, pressing and
holding in the (BK) key for one second will instantly select Menu #17 ( CW
DELAY ) .
6. To practice your CW sending (without transmitting), press the (BK) key to make
the “

” icon disappear. Now, pressing the key will cause the CW sidetone to be heard,
but your radio will not be transmitting a signal on the air.
7. You can adjust the CW sidetone volume level via Menu #44 (SIDETONE). To adjust the
CW sidetone volume level:

Press and hold in the key for one second to enter the Menu mode.

Rotate the knob to select Menu #44 (SIDETONE).

Rotate the knob to select a new level; on the arbitrary scale of “0” ~ “100,”
the default value is “50”.

When done, press and hold in the key for one second to save the new setting
and exit to normal operation.
